IMPRVENIENT IN LED-PENCILS.I

Specification forming part of Letters Patent :.No. 136,319, dated February 25, 1573.

To all whom it may concern:

Be it known that I. JOSHUA GRAY, of Medford, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Lead-Pencils, of which the following is a speciication, reference being had to the accompanying drawing.

My improvement consists in combining with a pencil, or the wooden part or lead-carrier thereof, a holder or cap, or the equivalent thereof, and a piece of India rubber or elastic erasive material, whereby the erasure or rubbing out of a pencil line or mark made with the lead of the pointed end ofthe pencil may be readily eft'aced simply by rubbing thereupon the said erasive piece of rubber.

In the drawing, A denotes a common peneil, of which a is the lead, and b the wooden holder of such lead. On one end of the pencil I attix a notched head or socket-piece, c, holding a convex piece of India rubber, d, and

having the same projecting` from it, so that by inverting the pencil and rubbing such piece d on a mark made with the lead of the pointed end ofthe pencil such mark may be removed. from the paper 'or article upon which 'it may have been made.

The convenience of a pencil so made, or so provided with' an eraser of rubber, or having one fixed to its upper end by equivalent means, so as to answer the purpose otl removing` marks made by the lead ofthe pencil, will be apparent to any person.

What I claim as my invention is- Gombining with a pencil, by means sub stantially as specified, a piece of India rubber, or like material, whereby marks made by the pencil may be effaced, as set forth.

JOSHUA GRAY.
